Abstract

Every version of the FTP specification has added a few new commands,
with the early ones summarized in RFC 959. RFC 2389 established a
mechanism for specifying and negotiating FTP extensions. The number
of extensions, both those supported by the mechanism and some that
are not, continues to increase. An IANA registry of FTP Command and
Feature names is established to reduce the likelihood of conflict of
names and the consequent ambiguity. This specification establishes
that registry. [STANDARDS-TRACK]
